The number of men is 850 MORE THAN that of women on a beach.
Let's re-write this "MORE THAN" sentence as a "LESS THAN" sentence:
The number of women is 850 LESS THAN that of men on a beach.
...there are 1,460 men
Now we see that to find the number of women, we subtract 850
1460 <--number of men
-850 <--subtract 850
----
610 <--number of women
how many people are there on a beach?
1460 <--number of men
+610 <--number of women
----
2070 <--number of people
